So I am wondering what people have observed about the length of the window that a female BRB is receptive? Typically when I see mating it only lasts for a couple weeks to a month for each female. However, I have this one girl who has been allowing the male to mate with her for over two months. She has been mated in years past, but has yet to produce a litter. Is this just inexperience?
I haven't been breeding BRBs for very long, so not sure if it is normal for a female to go this long.
